Puberty is when your body starts to slowly change into an adult body. Hair grows in places it didn’t before; breasts, the penis and testicles get bigger; periods start; voices get deeper.
This is when your body becomes sexually mature. In many people, this means that your body can make babies.
It usually happens between the ages of 10 and 16, but everybody is different. Some go through puberty earlier, and some later. It’s perfectly normal.
If you’d like more information about puberty, you could try speaking to a trusted adult or contacting us on the Meic helpline.
